I'm not sure who posted the stuff about the Agatha Christie book "And Then There Were None" but I posted that exact thing verbatim on another site.
In any case, as far as that book goes it's interesting that in an interview about the end of the Red John story arc with Bruno Heller he said: "Yeah, you can expect more deaths of suspects; I think I can say that without giving too much away. It’s not a Seven Little Indians thing, where one drops dead every week."
The reference to "Little Indians" rhyme might be significant because that is both the inspiration, concept, and original title of "And Then There Were None."
It was Christie's most financially successful mystery, and employs the red herring of a faked death. Wargreave "the hanging judge" fakes his own death only to reappear later as the killer.
Heller is a clever guy. And like most clever guys, like Red John, and Jane, they take pleasure in dropping little hints and seeing if their audience is smart enough to figure it out. Why mention the Little Indians unless it was a possible illusion.
Partridge is my suspect without a doubt. He knows exactly what to do to fake his own death and to trick other forensic investigators. It's also clear that he's working with someone, and that person might also be a forensic guy. For the record Wargreave also had help to fake his death in Christie's novel.
